Here's how it works:
* Divergent Boundary: The Red Sea is a classic example of a divergent plate boundary. This means the two plates are moving away from each other.
* Seafloor Spreading: As the plates separate, magma rises from the Earth's mantle and solidifies, creating new oceanic crust. This process is called seafloor spreading.
* Rift Valley Formation: The continuous separation and creation of new crust results in a depression, or rift valley, along the boundary between the two plates.
* Red Sea Expansion: The Red Sea continues to widen as the Arabian Plate moves eastward and the African Plate moves westward.
So, the Red Sea Rift Valley is a direct consequence of the ongoing separation of the Arabian and African plates.
